Understanding GraphQL Subscriptions

Welcome! In this lesson, we'll dive into GraphQL Subscriptions, a powerful feature for real-time data updates. Imagine getting instant notifications or live data streams directly from your server!

Subscriptions allow clients to receive updates automatically when data on the server changes, without needing to constantly ask for new information.

GraphQL has three main operation types:

• Queries: Used to fetch data. Think of it as a GET request.
• Mutations: Used to modify data (create, update, delete). Like POST, PUT, DELETE.
• Subscriptions: Used to subscribe to real-time events, receiving data as it happens.

Each serves a distinct purpose in interacting with your API.
